UNIT

To aZZ'wLom/a' may concern:

113e it known that I, LEROY NixoN, a citizen of the United States, and a resident of Murray Hill, in the county of Union -vand State of New Jersey, have invented certain. new and useful Improvements in Milking whereof the fication, reference being had to the accompanying. drawings.

The invention relates to milking appara tus `eof the type1 by the aid of ya pulsating suction mechanism whichis ,not only automatic in its operation, but whose'principle of operation is such as to' tend to, effect a natural flow'of the milk without any discomfort or harmful ...effects upon :the producing animal.

'Ih'e invention is directed to la milking device having the above general characteristics Apparatus,

and in which the various constituentV elements arel grouped to forma and, to this end, preferably ED STATES Amiriam oFFics. f

The various invention are so grouped as tion and pressure alternatively or cycle-wise, so as to bepulsative in effect, and in which. the periods offsuction. are of comparatively duration than the intervening pres- Infthis way an easy gradual draft is effected 'upon' the animal during thev suction period and'ample time afforded to facilitate the readyfiow'ofthe milk, without in anyway interfering with the rapid disposal of the drawn 'quantity during the coininvention lends itself readily to' em-'- a roller 13,;mounted of the yyoke extension l0, -of the :piston rod 9.

A spur pinion 15, -meshes with. a gear 16, on. the 'operating shaft 5, adjacent the bearing standard 7 said pinion and l,gear serving as gearing for ythe drivev of the cam motor ...14.

These valves are adapted for alternate action and they precise manner of their coperation will be more clearly explained hereinafter.

To the'nipple 20, is attached a trunk tube 27,y leading to a series of terminals not hich two I attainthe best understood Figure I, is a plan view` conveniently illusare illustrations simiof a vslightly modified elements comprised by my to constitute a .y ateiteafseptlzo, 192,1.-

Sincesuch devices )are well known in this art, their illustration in the present conne'ction has been deemed unnecessary.

The operation of the above described forml of my inventionis as follows:

After the teat cups are l the device is set in motioncjAs the pistony 8, is drawn outwardly, the suction createdl in thevcylinder 3, causes the valve disk'25, Vto yield automaticallyv against the tension of its seatingzspring-26, so that the milk is drawn through the tube 27,and into the i fittingy 19,

the valve 22, `being at'thesame time, held closedby the force'of the suction.v During the return stroke of the piston, the milk is forced out ofthe Hitting, and discharged 4into 4the receptaclev 2, through' the outlet branch 2 1, ofthe tting19. During this period the action. of' the valve is reversed, i. e. the valve 25,' is forcedto yield while the valve`22, is maintained lin its closed position.V vIt is to be noted that-by reason of thecharacter'of the operating cam disk 11, a substantial dwell occurs -at the completion of the suction stroke of the pis'- l ton, so that ample timeis afforded. to facilitate the readylow of the milk Thisgis of particular importa-,nce in order Vto permit a Vgradual drawing of the milk from 'the animaljunder the force of the vacuum before expulsion into the 4receptacle. v-

' Referring now to" the modified formof the apparatus. shown in Figs. vIII, and 1V, it will benotedthat the grouping of the constituent elements `is similar toy that shown in the previous form. In this instance, the

` suction4creatingelement'is inthe formof a diaphragmfpu'mp; consisting of-a'f cup or bowl member 30, which is provided with the milk inlet 3l,l andan outlet 32, controlled bya valve33'.' The flexiblerdiaphragmA 34,

of the 'pump is coupled means of a inetall36, fulcrumed to` Y. integrally :formed lic connector 35, to thexouter end of a lever a Ybracket 37, preferably vwith the cover; .Inter-1 mediate its ends, said lever'carries a roller'38,
